Two little worlds that grew up around tiny things finally collide again. Nanoblock, the brand of micro-sized building blocks, keeps chipping away at the Tamagotchi universe one centimeter at a time — and the third batch of its blind-box mini figures, mininano Tamagotchi vol.3, is set to land in Japan on September 30, 2026.
If you have not seen mininano before, here is the gist. Nanoblock is a Kawada Toys brand of micro building blocks, far smaller than the classic bricks most of us snapped together as kids. It is famous for licensed character mini kits. Mininano takes that idea and shrinks it again into its blind-box line: tiny, cute, sealed single builds sold at random from a box. You do not pick your character. You pull a pack, open it, and find out who came home.
The third series in this ongoing lineup carries the Japanese catalog code NBMC_97 and brings six Tamagotchi characters:
- Ginjirotchi
- Potchitchi
- Yattatchi
- Lovelitchi
- Melodytchi
- Makiko
Each finished mini build stands roughly 1.3 inches tall — about 33mm — and the box spec comes in at 32mm wide by 33mm tall by 20mm deep. These are pocket-sized squares of pastel charm, made to sit on a shelf, a desk, or right next to your actual virtual pet.
Mininano keeps the blind-box rules simple. One box holds six figures. Buy a full box and you complete the whole set of six, no doubles, no hunting the last straggler down. Single packs are packed randomly, which makes each one a small gamble — and so closes the loop for collectors who chase the full lineup.
For some figures, nanoblock leans on printed stickers to nail the details we already know by heart. Lovelitchi's and Melodytchi's eyes and mouths, and Makiko's hair, are reproduced as fine printed stickers rather than brick-built. It is a small touch, but it is the difference between a cute block and a figure that reads as the character at a glance.
None of this mininano fandom exists in a vacuum. The first volume — mininano Tamagotchi vol.1, released in Japan on July 5, 2025 — opened the series with Mametchi, Kuchipatchi, Mimitchi, Memetchi, Furawatchi, and Oyajitchi. That a wave two and now a vol.3 exist at all shows this is not a one-off novelty; it is a running themed series with its own growing set. And it makes sense. Tamagotchi itself launched in 1996 by Bandai, close to three decades ago now. The people who raised that first blinking egg are grown, and a chunk of them spend their money on the same kind of nostalgia they felt as kids — except now the plastic is a tiny brick kit you build with your own hands.
For a fan site that lives and breathes virtual-pet charm, that mashup of clicking buttons and clicking bricks feels right at home. Vol.3 is a clean, gentle entry point if you have somehow stayed out of mininano until now: six cute characters, one tidy full-box set, and a medley of nostalgia served in pastel. Whether you collected vol.1, skipped it, or are just discovering what a 33mm building-block Tamagotchi even looks like — this one arrives in Japan on September 30. Worth a look before the box sells out.
